Eh, he's not allowed to check in code to the main repository without someone who has C++ readability approving it first. Since code would need to be reviewed to be checked in anyway, it's not really a significant hurdle to get approval since almost everyone has C++ readability and the code review tool reminds you when approval is needed.

That being said, having looked at some of his code he would probably have to significantly modify his style to get readability.
